Cantrall The Michigan Entomological Society traces its origins to the old Detroit Entomological Society and was organized on 4 November 1954 to ". promote the science of entomology in all its branches and by all feasible means, and to advance cooperation and good fellowship among persons interested in entomology." The Society attempts to facilitate the exchange of ideas and information in both amateur and professional circles, and encourages the study of insects by youth. Membership in the Society, which serves the North Central States and adjacent Canada, is open to all persons interested in entomology. There are three paying classes of membership: Student (including those currently enrolled in college or graduate programs) - annual dues $2.00 Active - annual dues $4.00 Institutional - annual dues $6.00 Sustaining - annual contribution 625.00 or more Dues are paid on a calendar year basis (Jan. I - Dec. 3 1). Memberships accepted before July I shall begin on the preceding January I ; memberships accepted at a later date shall begin the following January 1 unless the earlier date is requested and the required dues are paid. All members in good standing receive the Newsletter of the Society, published quarterly. All Active and Sustaining Members may vote in Society affairs. All dues and contributions to the Society are deductible for Federal income tax purposes. SUBSCRIPTION INFORMATION Institutions and organizations, as well as individuals not desiring the benefits of membership,may subscribe to The Greathkes Entomologist at the rate of $6.00 per volume. The journal is published quarterly; subscriptions are accepted only on a volume (4 issue) basis.

Copyright @ 1974, The Michigan Entomologist Society THE GREAT LAKES ENTOMOLOGIST OVACARUS PEELLEI, A NEW SPECIES OF MITE (ACARINA: PODAPOLIPIDAE) ASSOCIATED WITH THE CARABID PASIMACHUS ELONGATUS Robert W. Husband Biology Ljepartment, Adrian College, Adrian, Michigan 49221 Recently, a new genus and species of rnite was discovered in association with the vaginal membrane or aedeagus of Clivina impressifrons, a pest which damages corn seed and seedlings in the midwest (Stannard and Vaishampyan 1971). This mite, Ovacarus clivinae, was described as a monotypic species of the genus Ovacams. In the process of examining another midwestern carabid beetle, Pasimachus elongatus LeConte, an unde- scribed species of Ovacarus was discovered. Larviform females were found near the external genitalia. All stages were found associated with oviducts and vaginal membranes, in a manner similar to that described by Stannard and Vaishampayan (1971). The new mite is here described as Ovacarus peellei. METHODS Beetles from which mites are to be removed are placed in individual beakers containing distilled water at 60°C for approximately 112 hour. The beetle is removed from the water and excess water is removed with tissue paper. The elytra are lifted, hind wings are moved aside and the beetle is visually inspected for mites. Seventy percent alcohol is forcefully sprayed on the beetle from a 112 pint squeeze bottle. This is done over a petri dish two inches in diameter. A second visual inspection of the beetle is made. The beetle is dried again with tissuc paper and the wings are returned to the original position. The contents of the petri dish are examined under a dissecting microscope at 10 to 30 magnifications. Podapolipid mites such as those found in this study are usually small, white and possess three pairs of legs. Males and larvifor~nfemales vary from 100-200 microns in length. Adult females are larger, 300-2400 microns, may be round or oval and may have from zero to three pairs of legs. Relatively few setae are found on all stages of these ~nites. Pyemotidae, Tarsonemidae and acarid deutonymphs are approximately the same size but have four pairs of legs. Acarid deutonymphs (hypopi) are very common. A ventral posterior cluster of suction discs characterize this stage. Remaining groups of mites are larger and usually more heavily sclerotized than podapolipid mites. Once found, mites are placed in vials containing 70% alcohol or placed directly on slides. Mites to be mounted directly are picked up with fine tip forceps, excess alcohol is carefully blotted away and mites are placed on slides in Iloyer's mounting medium. After the coverslips arc placed in position, slides are placed on a warming tray (40'-45°C) at least overnight. The next day, slides are labeled completely and edges of coverslips are ringed with lacquer (nail polish). All measurements and drawings are made with the aid of a Wild microscope drawing appar;l tus. 0 V,4 CA K US PEEL I. El. n. sp. 0. peellei is distinguished from 0. clivinae by the following characteristics: larviform female with length of setae verticales internae nearly as long as setae verticales externae and setae scapulares externae, setac vertic;~les esternae nearly 112 the distance between setae verticales internae and setar scapulares externae; male with fourth pair of legs more developed and more lateral in position than the fourth pair of legs of the male of 0. clivinac; one pair of propodosornal setae in contrast to three pairs in 0. clivinae; no coxal setae apparent in contrast to four pairs in 0. clivinae; spicules at apex of aedeagus longer than corresponding spicules in 0. clivinae.

As reproductive organs of female develop, the shape progresses from egg-shaped to spherical and genital opening anterior to opisthosomal setae elongates. Chelicerae and gnathosomas of adult females of Archipolipus canthoni develop inside exoskeletons of larviform fernales of (his species. Lack of this phenomenon in 0. peellei and nearly equal size of chelicerae in both mature and immature females indicate Iieotenous development in 0. peellei. Male. (1:igs. 1, 2). Gnathosoma. Width about 114 that of idiosoma; wider than long, ventral microsetae, dorsal setac inconspicuous. Pedipalps reduced, rounded; length of cheliccrae ca. 112 width
